...no longer relies on Manuel's repo hostig a version of "bignum" that actually
contained bignumber.js. This moves bignumber.js internally and removes bignum
from the browser build process. Also adds a bitcore.Bignum that links to the
right thing. In node, browser.Bignum is require('bignum'). And in the browser,
bitcore.Bignum is is now Bignumber.js (same as before ... except bignumber.js
is now inside bitcore).
Generating random numbers properly depends on the platform. The new
getRandomBuffer method does the right thing on the right platform. It will
sometimes fail due to insufficient entropy. The getPseudoRandomBuffer class is
also provided that will never fail, but it is not cryptographically secure and
should not be used for keys.
This adds a new Message class with static methods for signing and verifying a
message the same way as bitcoind. (In a nutshell, messages a prepended with
"Bitcoin Signed Message:" before being hashed and signed).
There is one important piece missing ... verifying a signature with an address,
and not a public key. I have not yet implemented this because the cryptography
interface of bitcore does not allow me to derive the public key from a
signature. This will need to be added before verifying from an address is
possible.
